How do Patents Intersect with Copyright?

v2ARE PATENTS AND COPYRIGHT MUTUALLY EXCLUSIVE OR CAN ONE USE BOTH?

As we have already learned, only patents protect ‘ideas’ from being copied so long as the patent tests are met. Copyright protects the expression of your idea , not your idea itself. Under copyright law, ideas are intended to be freely shared so you cannot ‘copyright an idea’.  You can therefore sometimes use patents and copyright together to protect different aspects of the same innovative output. 

The question of whether or not patents & copyright are mutually exclusive is illustrated in the examples below:

tech drawing

EXAMPLE 1: TECHNICAL DRAWINGS OF PATENTED INVENTIONS

Nina invents a new type of machine for which she obtains a patent. She includes in her patent application engineering drawings of her invention that she drafted herself. Under patent law, Nina can protect the machine (the actual physical invention) and can prevent anyone else from making or selling the machine.

Separately,  she would also be able to protect the engineering drawings against copying under copyright law. Because copyright law protects against the reproduction of a work in different dimensions, she might also be able prevent someone from making the machine based on the engineering drawings as an unauthorized three dimensional representation of her two-dimensional artistic work.

Not necessarily. Some countries exclude copyright protection for three-dimensional representations of functional products so, in these jurisdictions, copyright protection might only help Nina if she wants to stop someone from copying the actual technical drawings of her invention. She wouldn’t be able to use copyright to stop someone from manufacturing her invention.
Whether or not this is a better strategy than invoking her patent rights is something to be determined on a case by case basis and, ideally, with expert advice. However, one should always consider the ways in which copyright law might be used to advantage, even if the primary method of IP protection is through a patent.
coding

EXAMPLE 2: PROTECTION FOR COMPUTER SOFTWARE

Max develops a new software program he believes will transform his startup company into a competitive player in the telecommunications software industry.

Most jurisdictions consider computer programs to be the subject of copyright protection. However, some jurisdictions also recognize software patents in specific cases. Patent and copyright in the same piece of software are therefore not necessarily mutually exclusive.

In countries that allow both forms of protection, Max might consider the level of protection that each offer in determining his IP strategy:

Level of Protection
Copyright Patent
Copyright only protects against the reproduction of all or a substantial part of Max’s computer code.

Someone can independently develop software that performs the same function as the copyrighted software and that software would not be infringing on Max’s copyright.

Similarly, even if the competitor refers to Max’s code in developing her own, if she does not substantially reproduce Max’s code then Max will have trouble enforcing his copyright.

Assuming that Max is able to secure patent protection, then his patent will provide a much more robust form of legal protection.

Even though it lasts for a shorter duration than copyright, the protection is more all-encompassing in that it prevents anyone from producing Max’s invention regardless of whether the underlying computer code was also reproduced.

Patent rights would protect Max against someone independently arriving at the same invention whereas copyright would not.
